Technical field

The present invention relates to a kind of electro-optical system, subsystem and element, relate to the high tolerance components that is used at ultimate fibre or multifilament optical fiber connection aligning optical fiber more especially.

Background technology

Communication channel based on optical fiber is the system of the selection in multiple national defence and commercial the application, because its high-performance and small size.Especially, fiber optics has " advantage (proved-in) " in long distance applications, such as the city to city and continent to continent communication cross-over connection lower because electrical-optical-electricity (E-O-E) conversion elements, fiber amplifier and optical cable need not the pure electricity system cost of coaxial copper cable of E-O-E with respect to use.These long haul fiber can have several hundred kilometers between terminal.

Only there is tens kilometers optical fiber in more short-range system usually between terminal, and only there is tens meters optical fiber in ultrashort distance (VSR) system between terminal.Be connected and the long-distance weak point of comparing that is connected although be used for the telecommunications of subway, access and Administrative Area and the optical fiber of data communication, the application of a large amount of these classes is arranged.The number of elements that adopts optical fiber to need in these type application is very big.In these short-range system, " advantage " of optical fiber is for E-O-E terminal reforming unit and support circuit, and it is very responsive to be connected the cost of passive and active electrooptical device between the terminal and equipment.Therefore, active and passive system, subsystem and element for the photoelectricity that in short distance and VSR system, has " advantage ", its average price must reduce.The reduction of average price will help to promote to judge the necessary unit capacity of investment on the high speed manufacturing technology.

Important composition active and passive fiber element and stube cable cost is the joints of optical fibre itself.Lock pin (Ferrule) and the relevant apparatus that is used to aim at lock pin (for example be used for the division sleeve pipe (split sleeve) that single fiber is connected, be used for many fine grounding pins (ground pm) that connect) have determined the cost of existing fiber connector.Generally need alignment member that optical fiber is aimed at active and passive device, and aim at two optical fiber, be used for removably linking and be used for being connected.Need the accurate aligning of two polished fiber ends, thereby guarantee that overall light loss in the optical fiber chain is equal to or less than the concrete optical connector loss budget for system.For single-mode telecommunication-grade fiber, this is usually corresponding to the connector fiber alignment tolerances less than 1000nm.In parallel optical fiber and single fiber chain, the connector of working under a plurality of G bit rates all must be assembled with the secondary element made from sub-micrometer precision.Still dislike inadequately if produce parts with this precision level, for the final products that make gained more economically, it must be finished with full-automatic, high-speed process.

The existing basic design above 20 years of present connector has not changed.The basic design of lock pin, division sleeve pipe and groove passes up to the seventies in 19th century.Traditional lock pin is a solid cylinder, and the axle center of cylinder has the hole, and the optical fiber that typically has a diameter from 0.125mm is inserted and secured on wherein.The external diameter of cylinder is generally 0.25mm, and its length is generally 10mm.For the overwhelming majority, the product on the market adopts identical therewith design now, but from different made and by different manufacture method manufacturings.To fiber optic applications, lock pin is made by mechanical-moulded sheet metal or zirconia ceramics usually for single optical fiber.In the rapid technology of multistep, the mold of zirconia sheet is become approx. dimension, add a little processing subsequently and grind this sheet to desired size and tolerance.For many fine application, lock pin is made by the thermosetting plastic that has injected quartz ball usually.Quartz ball makes the thermal expansivity of composite plastic-glass material system more approach quartz fibre than pure plastics.Usually can accept, present joints of optical fibre manufacturing cost is excessive.If optical fiber becomes the selection of the communication media of short distance and VSR application, the cost of making the joints of optical fibre must reduce.

Imprint process has been applied in the manufacturing process of low-cost production in enormous quantities part.Impression is the manufacturing process of the workpiece of compressing such as metal tape between the punch die external member to reservation shape or pattern.The punch die external member can be carried out various coining manipulations on workpiece, such as cutting, shaping (for example, punching, stretching, bending, formation flange and bound edge) and forging and pressing (for example, embossing).Usually, being shaped is meant the coining manipulation that does not change thickness of workpiece substantially, and forging and pressing are meant the coining manipulation of abundant change thickness of workpiece.Compare with the zirconia sheet of machining mold or the technology that charges into quartzy thermosetting plastic of mold, impression is comparatively faster technology.

Yet imprint process does not have effect for the part that can accept tolerance that has that manufacturing is used for photovalve.Authorize people's such as Balliet U.S. Patent No. 4,458,985 and instructed a kind of joints of optical fibre.Balliet has introduced some roughly can be by the connecting element of embossing or imprint process (for example, col.3,20 to 21,55 to 57 row) manufacturing.Yet Balliet does not provide this imprint process can use disclosure, has only proposed to make the available disclosure of the imprint process of part in the 1000nm.

In our " being used to make the impression system of close tolerance part " by name, be filed in the unexamined U.S. Patent application [sequence number does not obtain] on July 15th, 2003, it is herein incorporated by reference in full, and we have introduced the part such as electro-optical system, subsystem and element of impression tolerance in 1000nm.Fig. 1 illustrates to be used to impress the synoptic diagram of system 10 that tolerance is lower than the photovalve of 1000nm.Partly, impression system 10 comprises impression pressing plate 20, one or a series of impression platform 25 and interface system 35.Each impression platform 25 can comprise utensil, such as the drift or the mould that are used on workpiece carrying out concrete coining manipulation, be used for the sensor of online tolerance and utensil protection and such as the miscellaneous equipment of welding machine.Impression platform 25 comprises a kind of structure of novelty, is used for aiming at the ground pilot punch with the tolerance of precision substantially with mould.Be included in the quantity of the movable element in the supporting construction when in addition, impression platform 25 is designed to be minimized in pilot punch to mould.Impression pressing plate 20 provides power for a series of impression platforms 25.Interface system 35 is convenient in conjunction with pressing plate 20 power with drift, but on the structure pressing plate 20 is separated from drift.Interface system 35 also allows each impression platform to separate, and makes the operation at a platform place can not influence the operation that another is located.

This accurate imprint process can be made the part of " 6 ∑ " the geometric tolerances band with 1000nm.On the statistics, this means that maximum 3.4 parts will not satisfy the dimensional requirement that has the 1000nm tolerance range to limit in per 1,000,000 parts.For normal distribution, in order to realize 6 ∑ technologies, the standard deviation of complete process must be less than or equal to 83nm[(1000nm/2)/6=83nm], suppose that process means keeps stable.In fact, tolerance must adapt to the deviation of process means.For the process means deviation situation of adaptation ± 1.5* ∑, MSD maximum standard deviation is decreased to 67nm[(1000nm/2)/7.5=67nm].Again, suppose normal distribution, for realize this point in the multi-stage process with n levels of precision, each of n level must have ∑/n^0.5.If n=4 in this example, then ∑ (every grade) is less than or equal to 33nm.

Therefore expect to have such precise light electric system, subsystem and element, it is in order to design with manufacturability that can the high speed imprint process that tolerance is produced in 1000nm.Also expect to have such precise light electric system, subsystem and element, it is in order to design with the manufacturability in the impression system of introducing in our unexamined U.S. Patent application (sequence number does not obtain).
